Park in Niblo or Darrell Pl and walk straight up the hill to a set of boulders past some trees. V0 to V8+ climbing. The area has been updated with a topo - not all climbs are listed as this is a guide to help you find which boulder is which. From there, the photo topos should get you onto the correct climb! Some of the angles on the drawn topo may also be slightly skewed.

Access issues inherited from Cooleman Ridge Bouldering

Please be sensible accessing the Horse Paddock boulders if walking in from the Kambah side and go around the horses rather than straight through the pen. Access from this side is at the end of Hake Street - drive past the pony club and park near the 'Arawang' sign.


3-5 minutes from Niblo or Darrell Place, uphill. There is a small walking track between the trees, or you can walk directly uphill through the scrub and blackberry. See area topo.

Ethic inherited from Cooleman Ridge Bouldering

While some of the harder climbs on the ridge were created by chipping, where previously no climb was possible, please leave your chisels at home. There are not so many climbs at the higher grades that they should be brought down to lower levels!
